[QUOTE="Crossbow, post: 911133, member: 47086"] You guys were way too hard on him. Full length dies are for first time resizing with brass that is new or fired from a different gun or in semi automatics to insure proper feeding, but using it on brass fired from the same bolt gun it will be fired from again leads to metal hardening and early fatique. Neck sizing is all you should / need to do otherwise so it holds the bullet properly. He was right and half the people who got on to him were wrong. That being said, the bullet seated with a micrometer helps only a little. With a good caliper and making small steps will make just as good a bullet. The problem is though, exactly what you identified with vld or hybrid ogive bullets is that the impact the collet improperly since the were machined with a more drastic curve so all the seating pressure is put in too small an area. The symptom is a sticking cartridge on the down stroke or even a "halo" ring you can see on the bullet after extraction. If you use the vlds or match bullets a lot stick with match grade dies that specify for use in match grade bullets or if you have deep pockets have a die set made just for the bullet you use. lightbulb [/QUOTE]
